UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented Sept. 29, 1908.

To all whom it may concern: I

Be it known that I, ANroN BECKER, of Columbus, in the county of Franklinand State of Ohio, have invented certain new and useful Improvements inUnderframes for Cars; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to underfrarnes for cars and more particularly toimprovements especially adaptable for short vehicles or cars such ascabooses,the object of the invention bein to provide simple andefficient means W ereby such underframe can be effectually sup ortedupon the car pedestals and which shalfpossess sufficient rigidity andstrength for the purpose for-which it is intended. I

With this object in view the invention consists in certain novelfeatures of construction and combinations of parts as hereinafter setforth and pointed out in the claims.

In the accompanying drawin s, Figure 1 is a transverse sectional viewiflustrating a car underframe embodying my improvements, and Fig. 2 is afragmentary view illusrating a slight modification. I

1, 1, represents Z-beams which are located upon and secured to thepedestals 1 (if the car over the journal-boxes. These Z-beams serve tosupport, through the medium of cross-beams 2, the center girder 3. Eachcross-beam comprises two members and each of these members consists of adiaphragm of pressed steel having laterally projecting flanges at itsedges. The inner 'flangeA of each cross-beam member is riveted to acenter girder member and to the upper flanges 5 of the cross-beammembers, a compression plate 6 is secured and extends over the centergirder. A similar compression plate 7 extends under the center girderand is secured to the lower flanges 8 of the respective crossbeammembers. The outer end of each cross-beam member is contracted somewhatin depth and forms a recessed portion 9. At this recessed portion 9 thecross-beam member is placed uponthe ad'acent Z-beam so as to partiallyembrace the latter, and the short vertical flange 10 of the cross-beamis riveted to the vertical web of the Z-beam, while, the

horizontal flange 11 of the cross-beam member is riveted to the upperhorizontal flange of the Z-beam.

The outer end of each cross-beam member is depressed so as to form aseat 12 in a plane somewhat below the upper edge of said crossbeammember for the accommodation of a side-sill 13. The cross-beam membersare thus provided at their ends with side-sill seats which are depressedsomewhat and serve to receive side-sills of moderate sizel Furringstrips 14 are located upon the crossbeams and their upper faces are madeto aline with the upper faces of the side-sills for the accommodationof'the car flooring.

As the cross-beam members are made of pressed-steel, I am enabled toprovide flanges which extend entirely around their edges, but if desiredthe flange at the extreme outer end of the cross-beam member between theseat 12 and the recessed portion 9, may be omitted as at 15.

By the term angle beams as used in the.

claims, is meant beams having webs and flanges disposed substantially atrightangles to the webs.

In a car of light construction where sidesills of the same size as thefurring strip will suffice, the seats 12 at the outer ends of thecross-beams may be omitted. Such construction is illustrated in Fig. 2.

Other slight changes might be made in the details of constructionwithout departing from the spirit of my invention and hence I do notwish to restrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire tosecure by Lettors-Patent, is,

1. A car underframe comprising anglebeams adapted to be supported uponthe pedestals of a car, and a center girder, crossbeams, each comprisingtwo members consisting of pressed steel diaphragms having flanged'edgessecured at their inner ends to the center girder and supported inwardlyof their outer ends upon the angle-beams over the pedestals.

2. A car underframe comprising anglebeams adapted to be supported uponthe car pedestals, and a center girder, cross-beams, each comprising twomembers secured to the center girder, each of said members having a 3. Acar underframe comprising anglebeams adapted to be supported upon thecar pedestals, and a center girder, eross-bearns supporting the centergirder upon said anglebeams, each of said cross-beams recessed near itsouter ends and partially embracing the angle-beams and secured to theweb and top flange of the latter, and each of said cross-beams having atits outer ends beyond its supports upon the angle-beams, seats forside-sills.

4. A car underf-rarne comprising anglebeams adapted to be supported uponthe car pedestals, and a center girder, cross-beams,

each comprising two members and each member consistmg of a pressed steeldiaphragm provided with flanged edges, the flange at the inner end ofeach cross-beam member secured to the center girder, and lower flangesof each cross-beam member secured to the adjacent angle-beam, eachcrosssill member projecting laterally beyond said angle-beam andprovided at its free end with a depressed seat for a side sill.

In testimony whereof, I have signed this specification in the presenceof two subscrib- ANTON BECKER.
